HDPE works fine. Here is an inch and a half piston made for my Mouse Musket, a coax with a 2 inch chamber and 1 inch barrel. It wouldn't take much to adapt this to other sizes. My barrel has an o ring seat, so the piston does not need a rubber face. I made it that way to make the piston lighter.spudtyrrant wrote:i made a metal piston gun it worked great for about 3 shots

i would be cool but i don't have any readily available hdpe nor any ability to accurately machine it (at the moment) i was thinking a hot glue piston do you think that would hold up to 400 psi

HDPE can most often use the same tools.
HDPE often comes disguised as a cutting board.

- Sheet of HDPE 7/8ths inch thick. The old original PVC pipe cap piston is sitting on it.
